Ok... please ignore my previous post about raid. Here is possibly complete drop rate info from the new raid. There are 3 chest types (in the area called the demonweb). How many and what types will be available on each difficulty, I don't know. I assume the end chest is the one with commendation of heroism, but I'm not sure. I'm skipping non-epic info as the quest is epic only (I think). As usual, each table is a server d100 roll. Random vendor trash is not listed, these are only special loot tables. I'm not listing the exact item names because I don't care.
The whole thing is ridiculous to be honest.

So... that's my middle finger for you, Turbine, for banning me, as I'd normally not release such info early. In a way I'm glad I don't play this, or I'd be another one of the sheeps running it bazillion times for a +5 tome chance. Let's do some calculations... epic elite run, 1 end chest, no optionals:
3%*50%*3%*10%*90% = 0.00405% chance for *random* +5 tome. Statistically it's one per... almost 25000 runs?
Sorry if my math is failing me... and good luck to all you addicted powergamers...

Edit: This ends my interest in the game, so no more such info from me, and of course you are free to ignore it as usual
